Application filed January 30, 1923. Serial No. 6158Zi2 To all whom itmay concern:

Be it known that l, Gnono-n \V. \Vnninn, a citizen of the United States,residing at Girard, in the county of Trumbu lland- State of ()hio, haveinvented certain; new and useful Improvements in Repeater 'lerminals fortolli Mills; and l do-de'elar' the following to be a full, clear, andexact description of the invention, such as willenable others throughthe repeater, the work becomes twisted to someextent, making itextremely diiiicult for the attendant to properly ide this work to therollers. t is the ob ect of my invention however to provide asimple andinexpensive, yet an e liiciei'i't and reliable terminal for the repeateror work returning guide, which will not only guide such work to the nextset of rolls, but will straighten the work if it has been twisted whilemaking the return bend from one set of rolls to the next. In carryingout this object, a further aim is to provide aterminal which willbelaterally expansible tosome extent to permit itto accommodate work ofdifferent sizes and to 'enable the work to be easily removed in case itshould by any possibility become jammed.

lVith the foregoing in view, the invention resides in thenovelsubjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure l is a plan view showing the application of the terminal to arolling mill.

Figure 2 is a side elevation of the terminal.

Figure 3 is a central vertical longitudinal sectional view.

Figure 4 is a horizontal sectional view on line 4 -4 of Fig. 2.

Figure 5 is a vertical transverse sectional View through the terminal,adjacent the work receiving end thereof.

Figure '6 is a view similar to Fig; $5,011 line 66 of- Fi'g. 4. 4

In the drawings above briefly described, the characters R and R"designate the first and second sets of rolls of a rolling-"mill forforming strips andbars; and-the letten G refers to the usual J-shapedrepeater or guide which returns the workiafterit leaves therolls it, inorder'thatitmay be guided into the. rolls it. Between the outlet end ofthe guide G- and the inlet guide 6; of the mums, the ii'np'rovedterminalT is located, this terminal being internally shaped toreeeivethe work from the guide G andstraighten it if it h'as becometwisted andthen direct it into the guide G.

in the preferred form of construction, the terminal T is of theformation disclosed in Figs. 2 to 6. The numeral 1 designates ahorizontally elongated base plate which is suit-ably connectedat 2 withthe outlet end of the guide G, a pivot being preferably provided at thepoint 2 inord'er that the outlet end ofthe terminal" may beproperlyalin'ed with the guide G under all circumstances. The rear end of theplate 1 is formed with a'throa't 3 which guides the work between a pairof elongated gui'dingand straightening members which arejmounted on theplate 1 and have their inner adjacent sides longitudinally groovedthroughout their lengths, as indicateda't 5, to form-"aguiding andstraiglitening passage for the work. decreases in cross sectional areafrom its inlet to its outlet end and is helically directed to someei'it'ent' as will be seen' by comparing Figs. 5 and '6. Thus, if thework has been twisted to'som'e extent wliilewpassing aroundth'e guide G,itwill gradually be straightened as it 1 passes- 'through the 'coactinggrooves; 5.

I mount the members 4 in such a manner that they may be moved outwardlyaway from each other to some extent, in order to accommodate them forthe handling of larger work and in order that the work may be removedfrom the terminal, in case it should by any accident, become jammed. Inthe preferred form of construction, the members 4 have lateral ears 6pivoted at 7 to similar ears 8 on the rear end portions of the bed plate1, so that the front ends of said members 4 may be swung outwarly asrequired. I prefer to provide these members 4 with outstanding ears 9near their This passage front ends which contact with the upper sides ofslotted ears 10 on the bed plate 1, clamping bolts 11 being passedthrough the two sets of ears in order that the members 4 may be heldrigidly after adjustment.

By the use of my invention, difficulties heretofore encountered areovercome in an expeditious manner and a device is provided which will beefficient and reliable and will greatl save in labor and time.

As excellent results may be obtained from the details disclosed, theymay be followed if desired. However, within the scope of the inventionas claimed, numerous minor changes may be made.

I claim:

1. A terminal for the work returning guide of a strip rolling mill,comprising an elongated laterally expansible work receiving andstraightening guide, closed at its sides and open at its ends, theinterior of said guide decreasing in cross sectional area from its inletto its outlet end and being helically formed to straighten the strip iftwisted in the work returning guide.

2. A terminal for the work returning guide of a strip rolling mill,comprising a base plate having means for mounting it in operativerelation with the return guide, a pair of elongated work guiding andstraightening members on said base plate having their inner sideslongitudinally grooved throughout their length to form a guiding andstraightening passage for the work, said passage decreasing in crosssectional size from its inlet to its outlet end and being helicallyformed to straighten the stripif twisted in the work returning guide,and means for mounting said members on said base and permitting lateraladjustment thereof.

3. A terminal for the work returning guide of a strip rolling millcomprising a base plate having means for mounting it in operativerelation with the return guide, a pair of elongated work guiding andstraightening members on said base plate having their inner sideslongitudinally grooved throughout their length to form a guiding andstraightening passage for the work, said passage decreasing in crosssectional size from its inlet to its outlet end and being helicallyformed to straighten the work, means pivotally mounting the rear ends ofsaid members on said base plate, and means for adjustably securing thefront ends of said members to said plate and for permitting lateraladjustment of said members.

4. In combination with a work returning guide of a strip rolling mill, aterminal comprising a base plate mounted in operative relation with thereturn guide, a pair of elongated work-guiding members on said baseplate having their inner sides longitudinally grooved throughout theirlengths to form a guiding passage for the work, means pivotally mountingthe rear ends of said members on said base plate, and means foradjustably securing the front ends of said members to said plate and forpermit ting lateral adjustment of said members.

5. The combination with a pair of rolling mills having reducing passestherein, of a horizontally disposed open trough return bend guideadapted to receive a strip from the passes of one mill and to reverseits direction towards the passes of the other mill and having a covereddelivery end, a base plate pivoted to the end of the guide provided witha covered receiving end matching the delivery end of the trough, and atwisting guide for the strip mounted on the pivoted base for delivery tothe receiving passes of the mill.

6. The combination with a pair of rolling mills having reducing passestherein, of a horizontally disposed open trough return bend guideadapted to receive a strip from the passes of one mill and to reverseits direction towards the passes of the other mill and having a covereddelivery end, a base plate pivoted to the end of the guide provided witha covered receiving end matching the delivery end of the trough, and atwisting guide for the strip composed of two co-acting sides adjustablymounted on the pivoted base and providing a guiding channel for thestrip.

In testimony whereof I have hereunto afiixed my signature.
